/**
|
||
|
|
* Map a list of items into an object.
|
||
|
|
*
|
||
|
|
* In the following example, a list of DomainPerms like the following:
|
||
|
|
*
|
||
|
|
* ```json
|
||
|
|
* [
|
||
|
|
* {
|
||
|
|
* "domain": "example.org",
|
||
|
|
* "public_comment": "aaaaa!!"
|
||
|
|
* },
|
||
|
|
* {
|
||
|
|
* "domain": "another.domain",
|
||
|
|
* "public_comment": "they are poo"
|
||
|
|
* }
|
||
|
|
* ]
|
||
|
|
* ```
|
||
|
|
*
|
||
|
|
* Would be converted into an Object like the following:
|
||
|
|
*
|
||
|
|
* ```json
|
||
|
|
* {
|
||
|
|
* "example.org": {
|
||
|
|
* "domain": "example.org",
|
||
|
|
* "public_comment": "aaaaa!!"
|
||
|
|
* },
|
||
|
|
* "another.domain": {
|
||
|
|
* "domain": "another.domain",
|
||
|
|
* "public_comment": "they are poo"
|
||
|
|
* },
|
||
|
|
* }
|
||
|
|
* ```
|
||
|
|
*
|
||
|
|
* If you pass a non-array type into this function it
|
||
|
|
* will be converted into an array first, as a treat.
|
||
|
|
*
|
||
|
|
* @example
|
||
|
|
* const extended = gtsApi.injectEndpoints({
|
||
|
|
* endpoints: (build) => ({
|
||
|
|
* getDomainBlocks: build.query<MappedDomainPerms, void>({
|
||
|
|
* query: () => ({
|
||
|
|
* url: `/api/v1/admin/domain_blocks`
|
||
|
|
* }),
|
||
|
|
* transformResponse: listToKeyedObject<DomainPerm>("domain"),
|
||
|
|
* }),
|
||
|
|
* });
|
||
|
